◆ G_list_element()

void G_list_element ( const char *  element,
const char *  desc,
const char *  mapset,
int(*)(const char *, const char *, char *)  lister 

General purpose list function.

Will list files from all mapsets in the mapset list for a specified database element.

Note: output is to stdout piped thru the more utility

Given file name, and mapset, lister() should copy a string into 'buf' when called with name == "", should set buf to general title for mapset list.
